Did you -DUSE_TCL_STUBS ? This is necessary when linkking against the
stubs library, it prepares the code to search the functions in the
stubs table at runtime, rather than in libtcl8.x.so (tcl8x.dll).

Probably they are loaded from the Tcl shared libraries (libtcl8.x.so or
tcl8x.dll). It will continue to work unless you upgrade Tcl or try to
wrap the extension into a starkit...
